South Placer Regional Wastewater and Recycled Water Systems Evaluation

Report Background

The South Placer Regional Wastewater and Recycled Water Systems Evaluation (Systems Evaluation) was developed to provide the South Placer Wastewater Authority (SPWA) with a baseline characterization of its wastewater and recycled water systems. As a part of this document a new 2005 service area boundary was defined. This boundary includes areas within Roseville, Rocklin, Loomis, and portions of Granite Bay and Placer County.

This document is the long-term planning tool for identifying and implementing necessary capital improvement projects to accommodate urban growth within the service area boundary. The document addressed system conditions as of June 2004 and anticipated buildout conditions.

The 2009 update brings the Systems Evaluation up to date with the following changes: 2006 changes in the SPMUD UGA boundary and land use, and to add Brookfield as an additional UGA; 2008 changes in the land uses and flow projections of the UGAs; and 2009 updates to the H20Map Sewer Model software, changes to the development timeline to reflect reduced rates of residential development, and a proposed rezone for the West Roseville Specific Plan which would result in higher buildout flow estimates. For the purposes of this study, June 2004 is still considered “current” and has not been updated to 2009 conditions.
